StaleConfig error on sharded cluster after successful logical restore

Description

We have sporadic failures on CI test test_PBM-1223.py when after the successful restore test executes db.countDocuments on sharded collection and mongo returns error:

Need to investigate the issue and possible workarounds, docs:

internals

flushRouterConfig

 

Next steps:

  • tries to reproduce it locally

  • investigate the issue and try to find out if there is a workaround

  • than we will see if we need to fix it, right now it seems it affects only PSMDB 5.0

  • decision about fixing

Environment

it fails only on PSMDB 5.0

please add to the docs “ensure that balancer and chunks autosplit is disabled”

This can be checked by executing sh.status() the field autosplit:

Possible resolution is to flush router config after the restore
